“…Nowadays, rapid decrease of petroleum stresses the importance of coals for covering the shortage of organic chemical feedstock [3,4]. Compared to the existing DCL performed at high temperatures, low-temperature DCL should be more promising in consideration of the fact that the formation of gaseous products and coke can be considerably reduced at low temperatures [5][6][7].…”

Activated carbon (AC) was modified by H 2 SO 4 and used as a support for catalyst. The Fe 2 S 3 /AC-T catalyst was prepared by deposition-precipitation method and used to catalyze hydrocracking of coal-related model compound, di(1-naphthyl)methane (DNM). The properties of catalyst were studied by N 2 adsorption-desorption, X-ray diffraction, and scanning electron microscopy. The result showed that ferric sulfate and acidic centers had synergetic effect on hydrocracking of DNM when using Fe 2 S 3 /AC-T as catalyst, the optimal loading of Fe is 9 wt.%. Hydroconversion of the extraction residue from Guizhou bituminous coal was also studied using Fe 2 S 3 /AC-T as the catalyst. The reaction was conducted in cyclohexane under 0.8 Mpa of initial hydrogen pressure at 310°C. The reaction mixture was extracted with petroleum ether and analyzed by GC/MS. Amounts of organic compounds which fall into the categories of homologues of benzene and naphthalene were detected. It suggested that the catalyst could effectively catalyze the cleavage of C-C-bridged bonds.

“…Pyrolysis was applied, over the years, to different substrates, e.g. to carbonaceous materials, such as coal or wood [7,8], biomasses [9,10], municipal solid waste [11], packaging [12,13] and tires [14,15] for energy and valuable chemicals recovery. Thanks to its versatility the process was also applied to the pyrolysis of carbon fiber composites (CFRPs) where energy recovery to sustain the process is coupled to the recovery of reusable carbon fibers [16,17,18].…”

“…The drawback of the method is the high production cost, inactivation of catalyst and serious environment pollution, etc. To overcome the drawback, several methods have been proposed, and preparation of BPCA from coal is one of such methods [Calemma V,1994] [Miurak, 2000] [Miura, 2001].…”

Pyromellitic dianhydride (PMDA) was prepared by an alkali oxygen oxidation of anthracite and selectively decarboxylation of pyromellitic acid (PA). Tetraoctyl Pyromellitate (TOPM) was synthesized by the esterification of PMDA with isooctyl alcohol. The influence of temperature and time on the yield of PMDA was discussed. The effect of the amount of catalyst, weight ratio of PMDA and isooctyl alcohol on the percent conversion of TOPM was also investigated. The results indicate that worthy chemicals such as PMDA and TOPM can be prepared from coal.
